Children know 'what'...a son knows the 'why'

John 3:12-17 (KJV)
If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things? [13] And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. [14] And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: [15] That whosoever believeth in him should not perish, but have eternal life. [16] For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. [17] For God sent not his Son into the world to condemn the world; but that the world through him might be saved.


"John 3:16" what a great verse.  The supporting verses to it...even the entire chapter is a real good snap shot of what's going on here.
One must first put ones self into the scenario. 
1. The messiah is walking the face of the earth.  As a man, a king, a servant and as God.  Clearly at times Jesus acts out those characters individually and wholly.  
2. Jesus is talking to his disciples in the context.  God intends us to be the reader and glean the information in order to edify us.  But there are 2 types of language in scripture---Doctrinal application for you to know and Doctrinal application, to you, in order for you to act upon the way God intended. 
Let me give you an analogy:  if I read about changing the oil in a car it is general knowledge and I get the point.  I understand how, why, what I need to do and all the steps I need to get to the end-state.  But until I read the actual manual with regards to the exact model and make of my specific car then I will never know how to exactly change 'my oil'.  You see, doctrinal application to you....God intends for you to achieve what God has intended for you to be.
3. so, why does the author here in John tell the reader the "what" of God sending His Son?  The answer is simple yet can be complicated if one does not slow down and read the words.  Ok, God intends for this people to know He sent His Son.  Yes, he did.  The question is never asked "why".  They don't need to ask it.  They know why. OT scripture tells 'them' why.  God was about to establish the Kingdom here on earth.  They knew it and were ready for it.  That is why they were instructed to give away all their belongings and money.  There was no need for belongings.  Clearly children, as the nation of israel is referred to numerous times...'children'.  Do you always tell your child 'why'?  No, sometimes we just need them to be doers.  God is dealing with His people the way He always deals with them.  In a manner of governing, ruling, creator/creature relationship.  So, matter of factly stating it...yes, God did send His Son, to the world, whoever believes will be saved.  Got it!




Galatians 4:1-7 (KJV)
Now I say, That the heir, as long as he is a child, differeth nothing from a servant, though he be lord of all; [2] But is under tutors and governors until the time appointed of the father. [3] Even so we, when we were children, were in bondage under the elements of the world: [4] But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law, [5] To redeem them that were under the law, that we might receive the adoption of sons. [6] And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father. [7] Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ.

So, now after reading the Galicians vs I have highlighted here, do you see a change in the language?  Yes, God is now talking to a group called the 'body of Christ'.  This body has a different doctrinal message.  ie....the 'to' and 'for' parts are different.  God is actually explaining the 'why' part to us.  That is the part that is awesome.  In my earthly life, when I talk to my adult son, I talk to him as someone who is my partner, my co-worker, my companion who I labor with.  God talks to us as Sons.  He wants the work done on the cross to be the vehicle that launches the body of Christ into a sonship relationship with Him a simple statment that clearly solidifies this is gal 1:16...Because, after all, the kingdom here on earth is not for the body of Christ...it is for the nation of Israel.  My promised heavenly body will have no reason to be on this earth.  

Ok, let's slow down here a minute.  I have a lot to learn in order to become the son God wants me to be. Yes, now you get it.  That's the edification process.  The laws are removed so we might receive this adoption into sonship, rom 3:9-22.  One can't serve two masters.   One has to learn how to work with the Father.  I want to know the 'why'.  I want to tell my Father what I learned and how I am helping Him build His kingdom.  That is the sweet savor to God's.  

Difference:
The Jews: they knew, in times past, they were sinners because of the Law...They know now that they are sinners (one should not dwell on it) but because of the Grace of God they are saved from His wrath.
The Gentiles: knew not they were sinners because they were lost, without God, and without hope....now, they know they were sinners but are now spared God's wrath because of Grace and with Faith believe it.

The short of it:  scripture is either to you or for you and don't settle for the what find out the why.
